Abstract (en)

[origin: WO2012033452A1] This invention concerns a joint construction 1 intended to be used between two extended tubes 2 and 3 in order to connect these tubes 2 and 3 with each other and where the joint construction 1 offers an open internal compartment 4 that, during use of the joint construction 1, is connected to the open inner compartments 5 and 6 of the relevant tube element. The joint construction 1 comprises a first joint half 7 and a second joint half 8 that are essentially identical, an arrangement 9 that holds the joint halves 7 and 8 and thus the joint construction 1 together and where the joint halves 7 and 8 each comprise a first part 12 and 13 and a second part 14 and 15. The first parts 12 and 13 make possible a connection of the relevant joint half 7 and 8 to one of the tubes 2 and 3. The second parts 14 and 15 of each joint half 7 and 8 face each other and comprise outermost free end parts 20 and 21 that are directed towards each other, have a circular form and can be rotated relative to each other around a common axis X. A sealing and glide arrangement 22 located between the end surfaces 23 and 24 of the outermost free edge parts and comprising two surfaces 26 and 27 that make contact with the relevant end surface 23 and 24. At least one of the end surfaces 23 and 24 of the outermost free edge parts of the second parts comprises a construction 25 that increases friction that functions between the end surface 23 and/or 24 and the side surface 26 and/or 27 of the sealing and glide arrangement 22 that makes contact with the end surface 23 and/or 24. The invention also concerns a ventilation arm 29 and ventilation system 32.
